ROLLING BACK TO 2.7 FROM 2.8

IF your problem is just with Gmoccappy, you might be able to fool your 2.8 system by copying an older version of Gmocappy.py to your current system. I think its moved to the bin folder on install but here is the source.
github.com/LinuxCNC/linuxcnc/blob/master...gmoccapy/gmoccapy.py

If the sim config works then there is most likely nothing wrong with Gmoccapy.
Some times the error messages are misleading.
For instance it mentions that a widget is missing usually means that an error occurred somewhere that stopped the loading of widgets properly.

The answer is not obvious from the information I have.

I see in your HAL file you use a bunch of other custom python components too.
I would start by removing anything not required to actually load the screen, then start adding things back until and error is noticed.

This was just added and or modified a few days ago. The errors at start of gmoccapy point directly to this code that was just added. I'm using gmoccapy from 3932 with no issues. Everything works as it should until the update below was pushed through.

yes I see the mistake now. It was a merge error.
I am not familiar with Norberts code so didn't see it right away.

Thanks for pointing me to the bug. Chris was right, a wrong merge of 2.7 to master caused the error.
I just pushed a fix to master. New gmoccapy release is nor 2.3.3.4

COlger81,
you will need to wait a little to be able to get the new release from buildbot, if you use github, you will get it immediately.

I did some changes to hal_mdihistory, so please report if there are still errors with MDI Input. I changed that widget to react same as a terminal window. If you use the arrow keys to select an item, it will be placed directly in the entry widget, so a push on the <RETURN> button will send the command to LinuxCNC. I did that to avoid the need to use a mouse.

Thanks Norbert

Norbert,
As far as the MDI is concerned, some people use "pyautogui" to map things in python such as matrix keyboards and physical buttons to mimic typing in MDI. Would the change to the code have an effect on this?
